The latest of the 1,242 calibres built by the Grande Maison in the Vallée de Joux is named Calibre 176. Developed, crafted and assembled in the Grande Complication workshops of the Manufacture, it combines the gyrotoubillon with a chronograph function. Jaeger-LeCoultre has developed an instantaneous digital-display chronograph boasting extraordinary precision that destine it to become a new watchmaking legend, since it is the first chronograph to be associated with a flying spherical tourbillon.
Once again, the essence of this model – the perfection of the function – is clothed in pure beauty beautifully expressed on its round dial. The latter is swept over by a single seconds hand that begins running as soon as the chronograph is activated, and of which the tip, when it stops, points to the subdivisions on a classic 0 to 60 scale bearing 10-second numerals for enhanced clarity.
Nonetheless, rather than counting its rotations on a subdial, the Jaeger-LeCoultre watchmakers have opted for an instantaneous digital display, composed of two generously sized apertures appearing side by side at 3 o’clock on the dial of the chronograph.
It is also worth noting that the chronograph function of the Master Grande Tradition Gyrotourbillon 3 Jubilee is of the single push-piece type, an historical feature reflecting that characteristic of late 19th century models.
The Master Grande Tradition Gyrotourbillon 3 Jubilee comes in a new extra-white platinum case measuring 43.5 millimetres in diameter and 15.5 millimetres thick. The superbly elegant bezel and lugs are adorned with a polished finish creating a delicate contrast with the satin-brushed case sides.

For the first time ever on a worldtime watch, this model enables the user to adjust the time in the travel time zone to the nearest minute. The worldtime function thus enables travellers to adjust their time-zone display to all continents and countries, whatever the time-zone difference.
For this new movement, the Dual-Wing system is divided into two distinct mechanisms: the first is devoted to displaying the local time, and the second to show that in a second time zone.
The two mechanisms share the same regulating organ but each has its own independent source of energy, thereby avoiding the losses due to interaction between the mechanisms. The operation of the dual time-zone display does not in any way influence the running of the watch, a fact that considerably enhances the precision of the watch.
Each mechanism has a 50-hour power reserve and, governed by a wish to achieve ideal userfriendliness, the same crown serves to wound both barrels.
The timekeeping barrel is wound by a counter-clockwise rotation, and the travel-time barrel by a clockwise rotation.
Two magnificent symmetrically arranged subdials lend a perfectly balanced touch to this horological creation: the first subdial at 2 o’clock sets the stage for the hour and minute hand; while the second at 10 o’clock hosts the hour and minutes of the worldtime.
Beckoning observers to travel and presented like a globe, the day/night indication and the hours disc are placed at 6 o’clock, a location that considerably facilitates their read-off. The single crown is used to adjust the travel time zone in position 1, and the local time in position 2, as well as to wind the mainsprings when in position 1. Turning the crown in a clockwise direction winds the standard time indication and, turning it in the opposite direction winds the travel time-zone indication.
Issued in a 100-piece limited series in 18-carat white gold, the Duomètre Unique Travel Time watch has been specially produced for the inauguration of the Jaeger-LeCoultre Place Vendôme in Paris, where it will be available as of November 20th.

The Master Tourbillon Dualtime housing an automatic movement, Jaeger-LeCoultre Calibre 978B, displays a second time-zone on a dial testifying to a degree of aesthetic perfection that is inseparable from technical genius.
On this model equipped with a reworked tourbillon carriage, the watchmakers of the Manufacture have made no compromises regarding its performance, reliability and sturdiness.
The titanium tourbillon regulator accompanies a high-precision automatic precision beating at 28,800 vibrations per hour and equipped with an unusual and extremely large balance featuring an inertia amounting to 11.5 mg x cm2.

In 2011, to mark the 80th anniversary of the Reverso, Jaeger-LeCoultre presented the Grande Reverso Ultra Thin 1931 in tribute to this iconic watch that has remained as unique as ever.
In 2013, the year of its 180th corporate anniversary, the Manufacture unveils the Grande Reverso Ultra Thin Duoface, an ultra-thin model revealing the watchmaking genius of Jaeger-LeCoultre by introducing a dual time-zone display on its back.
Pivot the case, and the magic weaves its spell all over again. While few can now be unaware that this smooth move will reveal a second dial, this model nonetheless springs a surprise effect with this second black dial featuring a “Clous de Paris” hobnail guilloché motif and displaying a main chapter ring with 12 subdivisions to display the second time zone, while the 24-hour indication appears below in the form of a circle bearing the words “NIGHT” on the left and “DAY” on the right.
A new push-piece, seamlessly integrated within the side of the case, enables comfortable adjustment of the second time zone in one-hour increments. In offering this new Duoface model in an ultra-thin case, the Manufacture Jaeger-LeCoultre is achieving a new technical feat.
There is no optical illusion here and the total thickness is indeed a mere 9.14 millimetres.
The mechanical manually-wound movement, Jaeger-LeCoultre Calibre 854/1, comprises 180 parts and its balance oscillates at a frequency of 21,600 vibrations per hour – while measuring just 3.80 thick.

Nestling in its 18-carat white gold case, the watch reveals the full force of charm by a ricochet effect. Like a luminous echo, diamonds dance across the sides of the case all the way to the crowns and the bezel, before unfurling like a diadem above the numerals.
The dial succumbs to the beauty of rare crafts while preserving the impeccable readability of all the functions. The collection’s characteristic hour numerals feature a contemporary shape stretching across the curve of a crescent that is hand-guilloché according to the ancestral tradition of this decorative art, and coated with a transparent blue lacquer.
The hour arc tops a disc providing a spectacular vision of the sky with the constellation appearing on a precious lapis lazuli plate. Offering a delightfully lyrical touch, the designers of the model have chosen to incorporate a shooting star as a means of customising time: via a second crown adorned with an inverted diamond, the mobile star serves to set a personal rendezvous with the stars.
Accentuating the celestial ambitions that make this watch a perfect instrument for making astronomical observations, a zodiac calendar on the dial serves to show the position of the constellations sat any moment of the year, by means of an annual calendar that governs the system of time display and measurement.
The mechanical automatic movement, Jaeger-LeCoultre Calibre 809, rotates the star disc at the imperceptibly gradual pace of one turn every 23 hours, 56 minutes and 04 seconds.

In both versions, one in steel with a sunburst silver-toned dial and polished rhodium-plated hour-markers, and the other with an eggshell-white dial and 4N gold-plated applied hourmarkers, the Master Ultra Thin 41 embodies a perfect blend of strength and restraint. One of the dauphine-type hands points to the hours, and the other to the minutes.
The operating mode of the automatic movement is discreetly indicated on the lower part of the dial.
At 12 o’clock, the Jaeger-LeCoultre logo features the association of two names evoking the complementary values of two visionary minds: that of the Parisian businessman and that of the entrepreneur in the Jura mountains who was always keen to take on the most daring challenges.
At just 3.30 mm thick, automatic Jaeger-LeCoultre Calibre 898C boasts a 43-hour power reserve. It is fitted inside a 41 mm-diameter case measuring a remarkably slender 7.48 mm.
